Innovative Composite Masts Look To Reduce Cost And Increase Efficiency Of Rail Electrification
The title of this post is the same as that of this article on New Civil Engineer.
This is the sub-title.
Engineering consultancy Furrer+Frey will this week unveil its innovative composite masts for rail electrification, which could revolutionise the way that rail electrification is undertaken.
Other points from the article include.
- Development has been undertaken with Cranfield, Southampton and Newcastle Universities and Prodrive and TruckTrain.
- The project was part funded by the Department for Transport and Innovate UK through the First Of A Kind competition.
- The first composite masts have been created and tested at St Bride’s feeder station, just outside Newport in Wales.
This Google Map shows the area, where the test will take place.
Note.
- The South Wales Main Line crossing the South-East corner of the map.
- Newport station is to the East and Cardiff station is to the West.
- The St. Brides feeder station alongside the railway, by the Green Lane bridge.
I would assume that the connection to the National Grid is via the St. Brides 25 kV Substation in the North-West corner of the map.
The article lists the features of the design.
- A typical steel mast weighs 750 Kg., whereas a composite mast weight just 80 Kg.
- I suspect that these masts can be lifted around by a couple of average workers.
- They have lower wind resistance.
- Piles can be less deep. The prototype piles are 1.25 m., as against many that are over four metres on recent schemes.
- The piles have sensors to detect, when they are out of kilter and need replacing.
- Currently, wonky masts need to be identified by hands-on measurement or observant drivers.
- Two masts have been tested to destruction, to see if they match the theory.
But this to me as an Electrical Engineer is the clincher.
Furrer+Frey GB head of UK projects Noel Dolphin says this about the new design.
When they do take it to a mass manufacturing stage, it will be without carbon fibre inside, which presents another opportunity. The other ultimate goal is that the structure is insulating in itself. It’s another big saving if you can remove the insulators on the electrification cantilevers, as they’re expensive in themselves.
It’s all going the way of much more affordable electrification.
I have a few further thoughts.
The Involvement Of Prodrive
Prodrive are best known for their involvement in motorsport, as the home page of their web site indicates.
But as their site also indicates they get involved in other forms of high-performance disruptive engineering, where their experience is relevant.
Prodrive build the prototypes, but won’t build the production masts, although I suspect, their expertise will be used.
The TruckTrain
TruckTrain is a concept with roots in Coventry University that could be off-beam enough to be the new normal.
I have updated my thoughts on the TruckTrain and it is now in a post called The TruckTrain.
My Conclusion About TruckTrains
I like the concept and I can’t see why it would not be successful worldwide.
The Involvement Of TruckTrain With Furrer+Frey
This puzzled me for a time, as undoubtedly, the TruckTrain will be able to use standard electrification.
But in the TruckTrain leaflet, they mention that the TruckTrain has been designed to use single-track short-terminals.
So did they approach Furrer+Frey to find out about electrifying short terminals and the Swiss company felt TruckTrain was a concept they could support?
Obviously, if the TruckTrain is developed to be a battery-electric train, some mini freight terminals will need the ability to charge the TruckTrain.
Could A TruckTrain Be Used to Support Electrification?
Would a TruckTrain be the ideal support vehicle to erect or repair electrification?
If you take the problem, when the wires have been damaged, a TruckTrain could get to the site at 100 mph, much faster than a truck on the road. It could also have a platform to lift the engineers for inspection and repair.
A TruckTrain could be more than just a transport system.
Conclusion
Furrer + Frey’s lightweight composite electrification masts are a good idea.
Teamed with TruckTrains, they could prove a very powerful freight concept, where new mini freight terminals are needed.
Russia Destroys Ukraine’s Dream
The Antonov An-225 Mriya was a unique aircraft.
It was the biggest aircraft in the world and was regularly used to move heavy or awkward cargoes around the world, as a reading of its Wikipedia entry will disclose.
Mriya is Ukrainian for dream.
But all that useful work has come to an end.
This article on CNN is entitled World’s Largest Plane Destroyed In Ukraine.
These are the first two paragraphs.
The world’s largest plane, the Antonov AN-225, has been destroyed during the Russian invasion of Ukraine, according to Ukrainian officials, generating alarm and sadness among the aviation world in which it occupies almost cult status.
The enormous aircraft, named “Mriya,” or “dream” in Ukrainian, was parked at an airfield near Kyiv when it was attacked by “Russian occupants,” Ukrainian authorities said, adding that they would rebuild the plane.
I know it’s only a plane and in the current scheme of things, that is a minor loss, but the Mriya has proved itself to be so uniquely useful in moving awkward cargoes, that the plane would surely have played a major part in the humanitarian relief and the rebuilding of Ukraine.
Given, that the plane would have surely been of use to the Russians, it just shows how utterly stupid, they have been in this war.
Lithuania To Germany Intermodal Service To Launch In April
duiThe title of this post, is the same as that of this article on Railway Gazette.
These are the first two paragraphs.
Lithuanian national railway’s freight business LTG Cargo is to launch a service carrying containers and semi-trailers from the Kaunas Intermodal Terminal to Duisburg in Germany on April 4.
Trains with a capacity of up to 36 semi-trailers and containers will run thrice-weekly on the 1 500 km route. This will be LTG Cargo’s first westward service operating in three countries, with operations in Poland and Germany handled by its LTG Cargo Polska subsidiary.tail
These are more information and my thoughts.
The Route
The route appears to follow a route from Kaunas to Warsaw via
- Marijampolė
- Šeštokai
- Mockava
- Suwalki
- Buchwalowo
- Bialystok
Note.
- The links on the names are to the town’s Wikipedia entry.
- The border between Lithuania and Poland is between Mockava ans Suwalki.
- There are freight yards and change of gauge facilities at Šeštokai and Mockava.
Some of these towns are probably worth a visit, especially if like me, you have Jewish ancestors from the area.
My father’s great-great-grandfather possibly came from Konigsberg in East Prussia and arrived in the UK around 1800.
The Russian And Standard Gauge Solution
Consider.
- Estonia, Latvia and Lithuania have Russian gauge railways which is 1520 mm.
- Poland, Germany, France, Italy and the UK have standard gauge railways, which is 1435 mm.
The solution has been to build between Kaunus and Šeštokai, to build Russian gauge and standard gauge tracks side by side.
Kaunas Intermodal Terminal
This Google Map may show the Kaunas Intermodal Terminal.
Note the rail yards in the middle of the map, have both Russian and standard gauge tracks.
Rail Baltica
The route taken is the standard gauge route of Rail Baltica, which is an EU project.
- It will run between Helsinki and Warsaw.
- Intermediate stops will be Pärnu, Riga, Riga International Airport, Panevėžys, Kaunas and Bialystok
- Vilnius will be served by a branch from Kaunus.
- The line will be double track.
- The line will be electrified with 25 KVAC overhead.
- Passenger trains will operate at up to 249 kph.
- Freight trains will operate at up to 120 kph.
- A tunnel will be built later between Helsinki and Tallinn.
Completion of the route between Warsaw and Tallinn is planned for 2026.
Rail Baltica I
Rail Baltica I is the first section of the route to be opened and is described like this in Wikipedia.
The name Rail Baltica is also sometimes used to mean the first phase of European gauge railway construction from the Poland-Lithuania border to Kaunas in Lithuania.
It opened in October 2016.
The new freight service will use this route to connect to Bialystok and Warsaw.
Conclusion
I have been on the roads in this area of Poland and rail freight services are needed to take the pressure off the roads.
Conference Calls For More Freight Routes To And From Spain
The title of this post, is the same as that of this article on Railway Gazette.
This is the first paragraph.
Salvador Galve, Chairman of the Railway Commission of the General Council of Industrial Engineers, presented the European Alliance for the Development of Railway Corridors in the Iberian Peninsula initiative at a conference held in Madrid on March 9.
These are some points from the article.
- Less than 4% of freight is currently transported by rail in Spain, compared with an average of 18% across the EU.
- The Spanish government wants to raise this to 20%.
- Incidentally, in the UK, rail freight is at a level of 5 %.
- Italy has seven main lines connecting it to its neighbours, Spain has only two!
- Spain also has a break of gauge, whereas the UK and Italy do not!
- Plans exist for more freight corridors in Spain, and linking these to ports in North Africa and logistics hubs in the rest of Europe.
- Zaragoza, could be turned into a key southern European logistics hub, linked by tunnels to the main line between Toulouse and Bordeaux.
But to me the most interesting plan is set out in this paragraph.
On March 1 the Infrastructure Ministry gave its provisional approval for study into the feasibility of converting the single track, non-electrified line from Huesca to Canfranc from 1 668 mm gauge to 1 435 mm gauge, ahead of any possible reconstruction of the through route to Pau in France in the longer term.
It has always been on my bucket list to visit the magnificent Canfranc station.
Wagons Ordered For Growing Freight Traffic
The title of this post, is the same as that of this article on Railway Gazette.
This is the first paragraph.
GB Railfreight and leasing company Porterbrook have placed an order for Greenbrier Europe to supply 50 JNA 60 m3 capacity four-axle box wagons for transporting construction materials.
Other points from the article.
- The wagons will be built in Romania.
- They will be delivered in the Autumn.
- Porterbrook research is indicating a possible increase of 35 % in construction sector traffic between now and 2034.
Certainly, judging by the number of posts about freight, the sector seems to be innovating and running more trains.
Freightliner’s New Livery
.As I passed through Ipswich yesterday, I took these images of Freightliner’s locomotives in their new livery.
Note.
- Freightliner’s new depot on the town side of the Great Eastern Main Line appears to be fully open.
- Freightliner’s Class 90 locomotives, which they received from Greater Anglia now seem to be in the new livery.
- Freightliner’s Class 08 shunter is also shown in the new livery.
It also looked like up to four Class 90 locomotives were parked by Ipswich station.
This Google Map shows the tracks at the Western end of Ipswich station.
Note.
- The Greater Anglia Class 755 train in Platform 1 of Ipswich station.
- The two Freightliner Class 90 locomotives in the old green livery in the locomotive parking.
- I wonder, if freight trains are now changing to electric haulage after being hauled out of Felixstowe into Ipswich Yard, before continuing their onward journey.
Yesterday, by the use of Real Time Trains, I found these trains changed to electric haulage at Ipswich.
- 0250 – 436K – Felixstowe North to Garston – Changed back to diesel at Crewe.
- 0912 – 496K – Felixstowe North to Trafford Park – Changed back to diesel at Crewe.
- 0932 – 497K – Felixstowe North to Ditton
- 1113 – 412L – Felixstowe North to Trafford Park
- 2046 – 410M – Felixstowe North to Trafford Park
- 2152 – 412M – Felixstowe North to Garston – Changed back to diesel at Crewe.
These are my thoughts.
Changing Locomotives At Ipswich
It seems to take about 25 minutes to change a locomotive from diesel to electric.
At Ipswich, this seems to fairly easy.
- The freight train from Felixstowe stops in Ipswich Yard to the West of the station.
- The diesel locomotive is detached and probably moved to the yard to the South of the station.
- The electric locomotive is moved from by the station and attached to the train.
- The train goes on its way using electric traction.
All locomotive movements don’t seem to be too challenging.
Could More Electric Services Be Run?
I found these paths yesterday, where services left Felixstowe and went South to London.
- Coatbridge – 1
- Ditton – 2
- East Midlands Gateway – 1
- Garston – 2
- Hams Hall – 2
- Lawley Street – 3
- Trafford Park – 5
- Wentloog – 3
This is a total of nineteen trains and currently only six are electrified between Ipswich and London.
Would Bi-Mode Locomotives Be More Efficient?
In GB Railfreight Plans Order For Future-Proofed Bi-Mode Locomotives, I wrote about how GB Railfreight were planning to acquire a fleet of bi-mode locomotives.
In the related post, I said this.
I feel that, as the locomotive must fit current routes and schedules, so I wouldn’t be surprised to see the following specification.
- UK loading gauge.
- Co-Co
- Class 90 locomotive power and operating speed on electricity of 3.7 MW and 110 mph.
- Class 66 locomotive power and operating speed on diesel of 2.5 MW and 75 mph.
- Ability to change between electric and diesel power at speed.
- Ability to haul a heavy freight train out of Felixstowe.
- Ability to haul passenger trains.
Stadler will have one eye on the fact, that if they get this design right, this order for up to fifty locomotives could be just the start.
These locomotives would be ideal for Felixstowe to Ditton, Garston and Trafford Park.
- They would eliminate changing locomotives on these routes.
- They would reduce carbon emissions and fuel usage.
- They would be able to run at at least 100 mph on the Great Eastern and West Coast Main Lines.
They might also open up other partially electrified routes from Felixstowe via London.
Felixstowe And Wentloog
Wentloog freight terminal in South Wales.
In Movable Overhead Electrification To Decarbonise Freight, I used the Ipswich and Wentloog route to show how a long route could be decarbonised by the use of moveable electrification.
Conclusion
It looks like a philosophy is emerging to decarbonise a large proportion of freight services out of the Port of Felixstowe.
Movable Overhead Electrification To Decarbonise Freight
The title of this post is the same as that as this article on Railway Gazette.
This is the first paragraph.
The use of a moveable overhead conductor rail to eliminate the need to use diesel locomotives at freight terminals where traditional fixed electrification equipment would obstruct loading and unloading is being demonstrated in the UK, and a trial in India is planned.
The Railway Gazette article also has two pictures, which show the overhead conductor rail in two positions.
Ipswich And Wentloog
In A Class 93 Locomotive Hauling A Train Between The Port Of Felixstowe And Wentloog, I wrote about running freight trains between Felixstowe and Wentloog using a Class 93 locomotive.
Currently, there appear to be three services a day each way between Felixstowe and Wentloog.
- They are diesel hauled.
- The Class 66 locomotive can’t travel faster than 75 mph.
- The route between Ipswich and Wentloog is fully-electrified.
- Other services that go from Felixstowe to the rest of the UK via London, are sometimes hauled by a Class 90 locomotive from Ipswich.
- Class 90 electric locomotives can haul trains at up to 110 mph.
This Google Map shows the layout of Wentloog freight terminal.
Fitting a moveable overhead conductor rail at Wentloog would surely allow carbon-cutting Class 90 locomotives to haul a train, between Ipswich and Wentloog.
How many other freight terminals can be electrified by installing a moveable overhead conductor rail?
Express On A Perpetual Motion Machine. Scientists Create An Electric Train That Will Charge By Gravity
The title of this post, is the same as that of this article on The Saxon.
These are the first two paragraphs.
The world’s first “infinity train” will recharge its electric batteries during deceleration using the force of gravity.
Scientists and engineers from the Australian company Fortescue Future Industries have begun developing the world’s first train that will be powered by gravity. The company plans to spend $50 million on this development over the next two years, according to the Daily Mail.
How Does The Train Work?
According to the article, the sequence of operation appears to be as follows.
- The train starts at the high end of the line.
- The train rolls down the hill to the low end of the line.
- As it descends, it will pick up kinetic energy due to gravity.
- Regenerative braking on the train will be used to charge the battery.
- The train will have a full battery, when it reaches the low end of the line.
- The full battery will then power the empty train back up the hill.
I have a feeling that this will work, where there is a full train coming down the hill and an empty one going up.
In an example, I will assume the following.
- The high end of the line is 100 metres above the low end.
- The train weighs 100 tonnes.
- The full load weighs 100 tonnes.
- Regenerative braking is 100 % efficient.
I can calculate these energy values for a train running down and then up the line.
- A full train just about to descend, which weighs 200 tonnes and is 100 metres up will have a potential energy of 54.4 kWh.
- Whilst descending, this energy will be converted to kinetic energy and the regenerative braking will transfer this energy to the battery, which will then contain 54.4 kWh of electrical energy.
- After descending, the full train, which weighs 200 tonnes and is zero metres up will have a potential energy of 0 kWh.
- After emptying, the empty train, which weighs 100 tonnes and is zero metres up will have a potential energy of 0 kWh.
- After ascending, the the empty train, which weighs 100 tonnes and is 100 metres up will have a potential energy of 27.2 kWh.
- When the train reaches the high end, there will still be 27.2 kWh left in the battery.
Note.
- After a trip, there will be some energy left in the battery to start the train rolling down the hill on the next trip.
- Effectively, the train is powered by the weight of its cargo, which in Fortescue’s case is very dense iron ore on its trains from Pilbara to the coast.
- In some ways the Infinity train carrying iron ore is a bit like an overshot water wheel, where weight is added to the wheel and this makes the wheel turn.
- The train is driven by the weight of the cargo.
It may look like perpetual motion, but the train needs to be loaded for each trip to increase its potential energy.
I will now look at a passenger train on the same route.
- The high end of the line is 100 metres above the low end.
- The train weighs 100 tonnes.
- I will assume there are 50 passengers in both directions.
- I will assume each weighs 80 Kg with baggage, bikes and buggies, which gives a weight of 4 tonnes.
- Regenerative braking is 100 % efficient.
I can calculate these energy values for a passenger train running down and then up the line.
- A passenger train just about to descend, which weighs 104 tonnes and is 100 metres up will have a potential energy of 28.3 kWh.
- Whilst descending, this energy will be converted to kinetic energy and the regenerative braking will transfer this energy to the battery, which will then contain 28.3 kWh of electrical energy.
- After descending, the full train, which weighs 104 tonnes and is zero metres up will have a potential energy of 0 kWh.
- After emptying and reloading, the empty train, which weighs 104 tonnes and is zero metres up will have a potential energy of 0 kWh.
- After ascending, the the empty train, which weighs 104 tonnes and is 100 metres up will have a potential energy of 28.3 kWh.
Note.
- After a trip, there will be almost no energy left in the battery to start the train rolling down the hill on the next trip.
- If the regenerative braking has an efficiency of less than 100 %, it would be unlikely to work.
But it would work, if an appropriate amount of energy were to be added to the battery at either or both ends of the route.
Could A Passenger Train Like This Work On A Real Route?
In the UK, there are several lines, where a rail line climbs a few hundred metres.
- Cardiff Central and Aberdare
- Cardiff Central and Ebbw Vale Town
- Cardiff Central and Merthyr Tydfil
- Cardiff Central and Rhymney
- Cardiff Central and Treherbert
- Glasgow Central and East Kilbride
- Llandudno Junction and Blaenau Ffestiniog
- Manchester Piccadilly and Buxton
- Manchester Piccadilly and Glossop
For the trains to work, I suspect the following is needed.
- Regenerative braking efficiency must be as close to 100 % as possible.
- The total number of passengers going down during the day needs to be at least the same as the total number of passengers going up.
- For passenger trains to work, an appropriate amount of energy needs to be added to the battery at either or both ends of the route.
Freight trains which are transferring weight down the hill will generally always work.
Conclusion
The Infinity Train will work well with heavy freight, but will probably need supplemental charging to work with passenger trains.
Both heavy freight and passenger trains will use less energy, than one working to traditional principles.
DB Cargo UK Successfully Trials The Use Of ‘Combi-Consists’
The title of this post, is the same as that of this press release on DB Cargo UK.
This is the first paragraph.
DB Cargo UK is trialling the use of ‘combi-consists’ to increase capacity, improve customer service and improve its efficiency.
The next four paragraphs describe the trial.
This month the UK’s largest rail freight operator ran a unique jumbo train from Belmont Yard in Doncaster to Barking, East London, carrying a mix of wagons for two altogether different types of customers.
The train consisted of two sets of empty wagons – 21 x MBA wagons for Ward Recycling and 18 x JNA wagons for FCC Environment – with an isolated DIT (dead-in-train) locomotive – in the middle.
The MBA wagons had previously been discharged at Immingham in North Lincolnshire and the JNA wagons discharged at FCC Environment’s new waste transfer facility at Tinsley in South Yorkshire.
Both sets of wagons were then taken to DB Cargo UK’s Belmont Yard depot in Doncaster where the jumbo train was assembled. The train travelled from Belmont Yard to Barking via Lincoln Central, Spalding, The East Coast Mainline, Hertford North and Canonbury Tunnel.
There is also a video embedded in the press release, which shows the formation of the train in detail.
This train is certainly efficient, as it uses less train paths, crew and fuel.
DB Cargo UK now intend to trial the concept on a greater portion of the East Coast Main Line and the Midland Main Line.
I have a few thoughts.
Could The Concept Work With Loaded Trains?
This trial was with empty trains, but would it be possible to use the concept with two shorter loaded trains?
Would there be advantages in terms of efficiency, if the following were done?
- Two container trains leave Felixstowe as a pair, with one going to Plymouth and the other going to Cardiff.
- They split at say Swindon and then proceed independently.
Obviously, all the weights would have to be in order and the locomotive would need to be able to pull the combined train.
Other possibilities might be.
- Stone trains running from the Mendips and the Peak District to London.
- Biomass trains running from import terminals to power stations in the Midlands.
- Trains delivering new cars.
- Trains delivering goods for supermarkets. Tesco are certainly increasing their use of trains.
I would suspect that DB Cargo UK have several ideas.
Could An Electric Locomotive Go In The Middle?
A Class 90 locomotive weighs 84.5 tonnes, as against the 129.6 tonnes of the Class 66 locomotive used in the trial.
So if the electric locomotive can be run dead-in-train, the weight would be slightly less.
But this might give a big advantage, if they ever wanted to run a pair of trains from Felixstowe to Plymouth and Cardiff, as per my earlier example.
- The trains would split anywhere on the electrified section of the Great Western Main Line.
- The lead train would go to Plymouth.
- The second train would go to Cardiff, which is now fully electrified.
There would appear to be possibilities to save carbon emissions.
Could An Electric Locomotive Go On The Front?
Some routes out of Felixstowe are fully-electrified from the Great Eastern Main Line.
It could be possible for the following.
- Two diesel-hauled trains to leave Felixstowe with ubiquitous Class 66 locomotives and form up as a combi-consist train in Ipswich yard.
- The Class 66 locomotive on the front is replaced by an electric locomotive.
- Both Class 90 and Class 92 electric locomotives have twice the power of a Class 66 locomotive, so both should be able to haul the combi-consist train.
The trains would split en-route with the electric locomotive hauling a train to an electrified destination.
This picture shows, what could be an experiment by Freightliner at Shenfield.
Unfortunately, I didn’t have a chance to ask the driver, if the Class 66 locomotive was running dead-in-train or helping the Class 90 locomotive with a very heavy load.
The picture shows, that the electric and diesel locomotives can work together, at the front of a train.
Since I took this picture, I’ve never seen a similar consist again.
Could A Bi-Mode Locomotive Go On The Front?
In GB Railfreight Plans Order For Future-Proofed Bi-Mode Locomotives, I talked about how GB Railfreight had started negotiations to purchase a fleet of powerful bi-mode locomotives from Stadler.
- Provisionally, they have been called Class 99 locomotives.
- The locomotives will be Co-Co bi-modes.
- The diesel engine will be for heavy main line freight and not just last-mile operations.
- I suspect that on diesel the power will be at least 2.5 MW to match a Class 66 locomotive.
These locomotives could be ideal for hauling combi-consist trains.
Would Combi-Consist Trains Save Energy?
This could be a big driver of the use of combi-consist trains and may push DB Cargo UK to acquire some powerful bi-mode locomotives.
Conclusion
Combi-consist trains seem to be an excellent idea.
GB Railfreight Plans Order For Future-Proofed Bi-Mode Locomotives
The title of this post, is the same as that of this article on Railway Gazette.
This is the introductory paragraph.
GB Railfreight is planning to order a fleet of main line electro-diesel locomotives with a modular design which would facilitate future replacement of the diesel engine with a battery or hydrogen fuel cell module.
The rest of the article gives clues to the deal and the specification of the locomotives.
- Negotiations appear to have started with Stadler for locomotives to be built at their Valencia plant.
- Twenty locomotives could be ordered initially, with options for thirty.
- The locomotive will be Co-Co bi-modes.
- The diesel engine will be for heavy main line freight and not just last-mile operations.
- They would be capable of hauling freight trains between Ipswich and Felixstowe, within two minutes of the times of a Class 66 locomotive.
- They will be of a modular design, so that in the future, the diesel engine might be replaced by a battery or fuel cells as required and possible.
They have provisionally been called Class 99 locomotives.
These are my thoughts.
EuroDual or UKLight?
Stadler make two types of bi-mode locomotives.
But the two types are closely related and open up other possibilities.
This paragraph from the Eurolight wikipedia entry, explains the various versions.
The type has been intentionally developed to support use on secondary lines without limiting power or speed performances, making it suitable for mixed traffic operations. Specific versions of the Eurolight have been developed for the United Kingdom market, and a 6-axle Co’Co’ machine for narrow gauge Asian markets, named UKLight and AsiaLight respectively. Furthermore, an electro-diesel locomotive derivative of the UKLight that shares much of its design, referred to as the Stadler Euro Dual, has also been developed and introduced during the late 2010s.
It looks like the customer can get the locomotive they want.
GB Railfreight would probably need locomotives to this specification.
- Slightly narrower than a EuroDual, to fit the UK loading gauge.
- Three-axle bogies to handle the weight of the larger locomotive.
- A body bigger than the UK Light to be large enough for the diesel engine.
- It would probably help if the locomotive could go anywhere that a Class 92 locomotive could go, so it could handle their duties if required.
This leads me to the conclusion that GB Railfreight will get a slightly narrower EuroDual.
Weight Issues
The weights of various locomotives are as follows.
- Class 66 Locomotive – 129.6 tonnes
- Euro Dual – 126 tonnes
- Class 90 Locomotive – 84.5 tonnes
- Class 92 Locomotive – 126 tonnes
All locomotives have six axles, except for the Class 90 Locomotive which has four.
I don’t think there will be any weight issues.
Power On Electricity
These are the power of the locomotives on electricity.
- Class 66 Locomotive – Not Applicable
- Euro Dual – Up to 7 MW
- Class 90 Locomotive – 3.7 MW
- Class 92 Locomotive – 5 MW
GB Railfreight can probably have what power is best for their routes.
Operating Speed On Electricity
These are the power of the locomotives on electricity.
- Class 66 Locomotive – Not Applicable
- Euro Dual – 100 mph
- Class 90 Locomotive – 110 mph
- Class 92 Locomotive – 87 mph
GB Railfreight can probably have what power is best for their routes, but I suspect they’d want it to be as fast as a Class 90 locomotive.
Power On Diesel
These are the power of the locomotives on diesel.
- Class 66 Locomotive – 2.5 MW
- Euro Dual – Up to 2.8 MW
- Class 90 Locomotive – Not Applicable
- Class 92 Locomotive – Not Applicable
To be able to handle trains, that a Class 66 locomotive is able to, 2.5 MW would probably suffice.
Could The Locomotives Use The Channel Tunnel?
I suspect that diesel locomotives are not liked in the Channel Tunnel because of all that flammable diesel.
But in the future, when there is a battery-electric variant, I would suspect that would be allowed.
In UK To France Automotive Train Service Launched, I talked about Toyota’s new service between Toton in England and Valenciennes in France via the Channel Tunnel. A locomotive with sufficient battery range might be ideal for this service, if it could handle the Market Harborough and Toton section, which is likely to be without electrification for some years.
Will The Locomotives Have Third Rail Shoes?
If their power on electricity is such that they can stand in for Class 92 locomotives, then there may be a need to fit all or some of the locomotives with third rail shoes.
As an example, they might be useful in taking freight trains to and from Southampton or the Channel Tunnel.
Conclusion
I feel that, as the locomotive must fit current routes and schedules, so I wouldn’t be surprised to see the following specification.
- UK loading gauge.
- Co-Co
- Class 90 locomotive power and operating speed on electricity of 3.7 MW and 110 mph.
- Class 66 locomotive power and operating speed on diesel of 2.5 MW and 75 mph.
- Ability to change between electric and diesel power at speed.
- Ability to haul a heavy freight train out of Felixstowe.
- Ability to haul passenger trains.
Stadler will have one eye on the fact, that if they get this design right, this order for up to fifty locomotives could be just the start.
It certainly seems a locomotive designed for the UK’s railway system.
The Anonymous Widower
